'Poor' in the Bible

If thou lend money to any of my people with thee that is poor, thou shalt not be to him as a creditor; neither shall ye lay upon him interest.

neither shalt thou favor a poor man in his cause.

Thou shalt not wrest the justice due to thy poor in his cause.

but the seventh year thou shalt let it rest and lie fallow; that the poor of thy people may eat: and what they leave the beast of the field shall eat. In like manner thou shalt deal with thy vineyard, and with thy oliveyard.

The rich shall not give more, and the poor shall not give less, than the half shekel, when they give the offering of Jehovah, to make atonement for your souls.
